Truck or main base 1 is shown as mounted on wheels 2. This base 1 isprovided with uprights or columns 3, 4, 5 (Figs. 1, 2). The column 3 hasloosely mounted thereon blank table 6, with which is fixed for rotationon the column 3, gear 7. The column 4 disposed between the columns 3, 5,has loosely mounted thereon long toothed gear 8 in mesh with the gear 7(Fig. 12), as well as in mesh with gear 9 fixed with blow table 10 onthe column 5. Piston rod-11 carries rack 12 in mesh with toothed segment13 mounted for rotation relatively with the column 4. ,Fixed with thissegment 13 is arm 14 carrying .pin 15 normally thrust by spring 16 tohave its head 17 enter the opening 18 in flange 19 iixed with the gear8. In the reciprocation of the iston rod 11, this pin 15 is a clutchdevice or connecting the intermediate driving gear 8 for efectinsimultaneous clockwise rotation of the ta les,6, 10, on the respectivecolumns 3, 5.

lBfz'ef description of .station sequence.

These tables 6, 10, are shown as having respectively, siX and eightstations of rest. Table 6 is shown as having station 1 (Fig. l) at whichmolten glass is supplied to the blank mold and packed down therein toform the neck finish therebelow. At therefrom, clockwise, is station 2at which the blank has the air chamber formed therein by blowing of airupward from below. Station 3 on the table 6 in proximity to the table 10is the transfer st-ation. In the travel of the blank from station 2 tostation 3, the blank is oriented to have the neck finish portion 3 theblank mold turned an additional nearly 180 to be in the position forstarting. Cooling, cleaning2 and washing of the molds ma. occuratstations 4. 5, 6, on the table 6,' wit the blank mold then coming tostation 1 forA a repetition of this cycle of operations. In practice,the stations 1, 2, may be shifted one or more positions away from thetransfer station to thereby allow period of time for carrying the blankbefore the transfer.

Opposing the transfer station 3 is station 7 on the table 10, at whichthe blank is received from the blank table and placed in the mold on theblow table. Station 8 is a position on the blow table at which the blankmay be allowed to set slightly if it be not desired to have the blowingoperation occur forthwith. Station 9 is shown as a first blowing stageand it is a 45o step or station of rest on the blow table, and station10 is shown as a second blow stage in those instances where it isdesired to effect the blowing of the blank into the form of the blowmolds by installments. Stations 1l, 12, may be stations for cooling orsetting' of the blown article of ware in the blow mold. Station 13 onthe table 10 is the station shown for removal of the finished or blownware from the open blow mold. Station 14 is an intermediate station fromthe station 13 in the travel of the blow molds to transfer station 7fora repetition of this cycle of operations. Each of these tables 6, 10,is shown as having an annular series of sectional molds.

Blank table.

Table 6 is shown as having radially disposed bearings (Figs. 4, 10) ineach of which is disposed a drum 21 having on its outwardportion a disk22.. This drum 21 is maintained in position in the bearings'20 by innerhead 23 providing central tubular guide 24. The disk 22 is provided withoutwardly extending ears 25, 26. In these lugs 25, 26, is mounted pivotpin 27 on which is pivotally mounted ears 28, of mold sections 29, 30.Upon this same pin 27 on the other Side of the ear 26 from the ear 25are pivotal mounted ears 32, also carrying the mold sections 29, 30 ofthe blank or parison mold.

These mold sections 29, 30, swing to closed position to provide a formor chamber 33 therein for the glass blank. Each of these mold sections29, 30, has an extension ear 34 to which is connected adjustable link 35extending through opening 31 in the disk 22 to crosshead 36 as held bypins 37 on the disk 22, extending inwardly, so that this crosshead 36 asreciprocable is held for rotation with the disk 22 and the blank mold29, 30.

Spring 38 normally urges the crosshead 36 away from the guide 24, forthus acting normally to hold the mold sections in closed position.

In this guide 24 is sleeve 39 carrying stem 40 upon which is mountedroller 41 coacting with cam 42 fixed on the column 3. Em-

bracing means 43 from the sleeve 39 coacting with the cam 42 beyond theroller 41 hold the sleeve 39 against rotation with the drum 21. Thesleeve 39 has shoulder 44 engaged by head 45 on stem 46 as extendingthrough the spring 38 to the crosshcad 36. There is thus Aprovided acoupling permitting in the outward throw of the stem 39 a yieldableclosing of the mold sections 29, 30, while in the reverse movement ofthe sleeve 39, the mold sections 2 9, 30, are positively thrown open.

Cam 42, (Fig. 2) on the column 3 has at the transfer station 3 a shortradius portion 47 into which the roller 41 may be thrustin swinging themold sections 29, 3U, into open position at the transfer station. At anidle station, the cam 42 has a short radius portion 4T permitting manualopening of the blank mold say for replacing a neck finish nipple, ormold elements without stopping the machine. At another idle stationspaced from the transfer station 3, this cam 42 has opening 48 normallyclosed by removable filler block 49. This permits removal andsubstitution of disk :32 and parts mounted therewith, This 'is ell'ectcdby removal of the block 49 so that the head 23 may be released andshifted radially inward and then taken out, whilel ai the same time thedisk 22 is released. The cam 42, with this block 49 in position, servesby coacting with roller 41 to maintain the mold sections 29, 30, inclo:.ed position at stations 1, 2, 5, and 6, on the blank table 6.

The disk 22 carries a pair of parallel outwardly extending rods 50 uponwhich is mounted crosshead 51 carryingl closure section 52 spaced fromthe blank mold sections 29, 30. Pivot pin 53 carried by the cross head51 carries neck finish sections 54, normally held toward each other inclosed position by leaf springs 56.

The disk 22 is normally held from rotation by a latch. This disk 22 hasseat .'17 (Figs. 5, 6) in which may enter head 58 of plunger 59 normallyurged into such seat 57 by helical compression spring 60 as mounted withsaid plunger in guide 61 fixed with the gear 7. This guide 6l mountsthis latch plunger 59 inward from the disk 22 to incline outward inengaging the disk 22 to hold the disk against rotation relatively to thetable 6. Accordingly, at stat-ion l, the disk 22 is latched to hold theblank mold in inverted postion and closed above the neck finish.

Charging station..

Mounted on the main base 1, at station 1, is auxiliary bracket 62 (Fig.6) carrying a cylinder 63 havingr stem 64 operable for upward thrustingof neck nish forming central stem 65. Also mounted on this aux iliarybracket 62 at station 1 is outwardly inclined bracket 66 carrying block67. l.This block 67 has ears 68 in which is fixedly mounted bolts 69coacting in slots 70 of ears 71 from horizontally extending cylinder 72(Figs. 6, 7, 8). l

This cylinder 72 has radially inwardly extending therefrom piston ro'd-73 operat' ing toggle 74 to swing jaws 75 on fixed pivot 7 6 as carriedby the block 67. In this radial thrust inward of the piston rod 73, thejaws 75 swing toward each other to grip therebetween lugs 7 6 on therespective mold sections 29, 30, and lugs 77 Von the respective neckfinish mold sections 54, 55. There is thus provided a locking device forholding the sectional mold closed at this station 1. This jaw lock iseffective, accordingly, to grip or engage through lugs on two pairs ofmold sections. The slots 70 allow such swinging of the cylinder 72 andthis piston rod 73 as to bring the jaws 75 into proper alignment ineffecting this holding of the mold sections in a closed position atstation 1 fr the charging operation.' Y.

Column 3 has'branched bracket 78 having arms 79, 80, (Figs. 1, 6)integral therewith.

Y This bracket arm 79 carries 'therebel'w auxiliary bracket 81' havingringportion 82 1n which'is funnel 83 under which the closed '30 moldsections 29, 30, ride for slightly lifting this n funnel 83 as *to itssupporting ring 82 thereby providinghfor 'snug seating between thischarging funnel 83 and the blank mold. The arm 79 additionally carriessupplementary bracket 84- carrying pivot pin 85 mounting cylinder 86having piston rod 87 connected to lever-arm 88 pivoted on fulcrum pin 89near the free end of the arm 79. Fixed with this arm 88 for swinging onthe pivot pin 89, is cylinder 9,0 having piston rod 91 downwardlyextendingA therefrom and carrying stem 92. In this tubular stem 92 isvalve stem 93 fixed with cap or closure member 94 having spheric topbearing portion 95 to provide a rocking bearing between this cap 94 andthe stem 92. In lifted position of the piston rod 91, the cap 94loosely'y hangs to have the bearing'95 clear of the stem 92 `and thevalve 93 seated or in closed 59 position. Upon downward action of thepiston rod 91 after such has been swung by the piston rod 87 intoposition over the ufunnel 83, the cap 94 adjusts itself for closing thefunnel -83 andis permitted to take such position by the rocking bearing95. This effects a lifting action of the valve 93, opening such valve topermit blow down or packing airto enter by way of the funnel 83 intotheblank mold 29, 30, for pack- 0 ing the 4charge of molten glass downin this out the nec-k'finish plunger 65,-

blow mold a such glass having been charged through this funnelv 83 intothe` blank mold at this station 1 before the cylinder 86 was effectivefor `116 and below flange 118 through which mashifting the cylinder 90into position over 65 the funnel 483.

The crosshead 52, centrally thereof between the rods 50, carries boss 96upon which ,is mounted roller 97. From this boss 96 there is extensionstem 98 also between the -rods 50. At this station l this roller 97 jBlow back up.

In the intermittent driving operation of the table 6 and gear 7, thischarge of molten glass is brought to station 2 for the blow back upoperation. i Bracket 102 carries locking cylinder` 72 with operatinglocking jaws 75 for holding the blank mold and neck mold sections closedat this station 2, in a manner similar to the holding of these moldsections at station 1.

The bracket 102 arises from pedestal or auxiliary bracket 103 at station2. Mounted on this pedestal 103 is cylinder 104 having piston rod 105.Lower guide portion 106 from the plunger 65 has its flange 'portion 107ride into guide channels 108 carried by bracket 109 arising from theside of the cylinder 104 away from the station 1. These channel guides108 serve as holding means` for the fiange 107 so that as the piston rod105 is thrust upward, its blow head 110 may have snug seating with thefiange 107. The bracket arm 80 carries fixed cylinder 111 from whichdownwardly extends piston rod 112 having fixed therewith flange 113having a series of annular openings 114 carrying rivets 115 looselytherein, but fast with flange 116 on dependingn stem 117, loosely inalignment with the piston rod 112.

This stem 117 is remote from the flange 1w chine screws 119 extend toxedly mount cap 120 with this stem 117. The loose connection provided bythe rivets for assembling the piston rod 112 withthe stem 117 and thecap permits on the downward thrust of this piston rod 112, an automaticseating of this floating baile 120 in closure position over the closedblank mold at station 2 for the blow backup operation in putting airinto the blank mold through the neck finish with the plunger 65 held outbelow or outside said neck finish.

.Up-ending the blank.

In the next step in the intermittent rotation of the blank table 6, 7,the latch'plunger 59, at once' the blank mold starts to leave station 2,has its roller 121 engage fixed cam 122 so that this plunger head 58 iswithdrawn from the seat 57 in the disk 22. This release of the disk 22occurs as roller 123 (Figs. 5, comes againsttooth 124 of segment 125ixedly mounted on the column 3. Clearance 126 permits i'oller 127 tomiss the tooth 124 and ride into seat 128. Accordingly, mesh relation isestablished between the rollers of the disk 22 and the toothed Seats onthe segment 125 of this gear, and in the continued travel of the table7, the blank mold Lip-ending roller 129 comes to removable seat 130.This seat 130 is mounted on the segment 125 by bolts 131 and isaccordingly removable. This seat takes the wear in the stopping of therotation of the segment, and as it is replaceable will permit supply7 otsections to take up any slackness for wear which may occur. Thisentrance portion ot the segment 125 has its teeth narrower than theteeth on the exit portion, or that portion of the segment 125 on theside of the removable tooth remote Jioni the station 2. This permits the180O rotation of the disk 22 with the disk 22 coming into engagementwith the segment after the disk or Just as the disk leaves station 2.-In practice, this has worked out for this first section ot the segmentto have an are extent on the column 3 of about 55 and 33. With the teethwider on the next portion of this segment 125 there is extent for thesecond 180 turning of the disk 21 of about 64 23.

As the steps for rotation of the table 6 are with the six arms, 60Osteps, the stopposition at tooth 130, station 3 or transfer station, isfollowed by station 4 with the blank moldnot quite fully righted tobring the bottom of the blank mold up. At this station 4, roller 132 isin tooth 133, and tooth or roller 123 is about to enter tooth 134. Theturning tor starting from the station 4 is slight and the tooth 133 mayride by the clearance 135, as the head 58 of the plunger 59 rides intothe seat 57 upon the completion of the full rotation of the disk 22.This holding of the disk 22 by the latch is maintained from station 4,and at station 5, 6, back to station 1 for release at station 2 in arepetition of this orienting cycle of operations.

Transfer station.

At the transfer station 10) the roller 129 is engaged by the tooth 130,and P the disk 22 is shifted the 180 from this station 3 bringing theparallel guides 50 to the upper position. U

Mounted on the segment 125 is cylinder 136 (Fig. 4) having piston rod137 in its thrust outwardly away from the column 3 effective to rocklever 138 on vertical f ulcrum 139 thereby causing depending portion 140from this lever 138, remote from the piston rod 137, to engage pin 40 tourge such pin 40 toward the column 3 to have the roller 41 in the recess47. This eects a swinging of the blank mold sections 29, 30, upon thepivot pin 27 into opening position to expose the blank as suspended inthe neck ring 54, 55.

With the blank thus suspended by the neck finish mold sections 54, 55,everything 'is in readiness for the transfer operation. Carried on thesegment 125 at this station 3 is horizontal cytlinder 141 having pistonrod 142 carrying head 143 in its thrust outwardly effective to engagepin 144 and thereby shift the crosshead 52 on the guide rods 50, towardstation 7 for carrying suspended blank 145 between partially closed blowmold sections 146, 147 (Fig. 20) as steadied by stem 98 passing overregister aligning rod 147 mounted by depending bracket 147 from arm 149.At this outward position for the blank, completion of the transfer isefteeted by release of the blank for deposit in this closed blow moldcomprising sections 146. 147.

The column 5 is provided with bracket 148 (Fig. 1) comprising arms 149,150. The arm 149 at its terminus carries vertical cylinder 151 fromwhich depends piston rod 152 carrying shoe 153 held in radial positionby stem 154 operating in guide 155 L(Fig. 10). Depression of this shoe153 by ownward thrust of the piston rod 152 strikes plunger 156 to shiftsuch downward against the resistance of spring 157 causing wedge 158 temove the neck finish ring mold sections 54, 55, away from each otheragainst the resistance of springs 56 thereby releasing the partiallyblown ware 145 for deposit in the blow mold sections 146, 147, as closedthereabout.

As herein shown blow table 10 is provided with eight stations or sets ofblow molds 146, 147, and the shifting of this table 10 (Fig. 20) asdriven from the gear 8 in mesh with the gear 9 is 45 as against 60 forthe blank table 6. These blow mold sections 146, 147 are mounted onfixed pivot 159. Each section has an ear 160 from which extends inwardlyan adjustable yieldable link 161 to cross-'head 162 radiallyreciprocable in guide 163. Each crosshead 162 carriesroller 164 ridingagainst cam 165 carried by the column 5. This cani 165 has its peripheryengaged by the rollers 164 on its maximum radius ortion for holding theblow mold sections 146, 147, closed for leaving transfer station 7 andcontinuing said holding at station 8,

mold have their roller 164 ride on this intermediate section 168 of thecam to station 7. Mounted on the cam 165 adjacent station 7 is cylinder169 having piston rod 170 eX tending therefrom to engage arm 171fulcrumed on pin 172 carried .by pad 173 on the cam 165 adjacentstation'14.

As this plunger 170 is thrust .outward from the cylinder 169, it hasledge 174 on the arm 171 engage pin 17 5 upstanding from the roller 164for thrusting the crosshead 163 radially outward. Guide rib 176 isengaged by this pin 175 in its travel outward at station 7 so that theremay not be impact as the mold sections 146, 147, are closed. If it bedesired to have the blank cooled to some extent before the final blowingoperation, such may' occurat station 8 and to this end adjustablebrackets mounted on the base 1 may be positioned at the succeedingstation or stations for blowing operation or operations. j

Finish blowing.

Mounted on the base 1 is detachable plate 177 mounting upright rods 178(Figs. 1,42,A

"20). Mounted on the column 5 adjacent the bracket 148 is bracket 179having arms 180, 181. The arm 180 has fixed therewith vertical cylinder182 with extension 183 there'- beyond coacting with the rods 17 8.

Between the extension 183 and the plate 177 and adjustably mounted byset screws.

184 (Fig. 17) is brace 185 having tongue and groove seat 186 (Fig. 18)for mounting auX- iliary support 187 having slot 188 engaged by bolt189. This permits adjustment in and out of cylinder 190 carried by thebracket 187, while the set screws 184 permit vertical adjustment of thisbrace 185. The cylinder 190 is shown as provided with piston rod 191acting through toggle 192 for swinging jaws 193 on bearing 194. Circularbase 195 as a mounting for the cylinder 190 similar to the mounting forthe cylinder 72, permits horizontal rocking of the cylinder 190 intocompensating position for acting through the toggle 192 in swinging thejaws 194 into locking position in coacting with ears 196 (Fig. 20) onthe blow mold sections 146, 147. There is accordingly a holding of theblow mold sections 146, 147, in locked position as the piston rod 191 isthrust toward the column 5. The cylinder 182 has downwardly extendingtherefrom piston rod 197 (Fig. 17) carrying blow head cap 198 fordescending into blow mold closing position on the blow mold sections146, 147

A secondary blowing may occur at station 10 with the locking cylindersupjio'rting rods 17 8 upstanding from plate 199 and the cylinder 182being carried by-arm .181 (Fig. 1). It may be desirable to have theblown ware held for an interval as distended against the mold and suchmay occur in the travel from the station 10 to the station 11, andthenceto the station 12. As passing the station 12, shorter radius portion 166of the cam 165, permits a relief of the closed blow mold sections 146,147, so that such may loosen or be partially started away from the ware.

Take o7?.

As the ware in the loosened blow mold passes from station 12 to station13 and there comes to rest, opening ofthe blow mold may occur. Mountedon the cam 165 adjacent the cam portion 166 is cylinder 200 havingpiston rod 201 extending to lever 202 mounted on fulcrum 203 carried bythe pad 173. When the blow mold comes to rest at takeolstation 13,piston rod 201 is drawn into cylinder 200 as flange 204 on the rlever202 engages the pin 175 and directs such pin toward the column 5 therebyswinging the mold sections 146, 147, at the take-off station into fullyopen position. At this takeoif station 13 bracket 148 has from its arm150 cylinder 205 downwardly from which extends'piston rod 206eliectivefor actuating pinchers 207 as controlled by walking beam 208 forengaging the neck of the ware as released by the mold sections asopening at this take-off station.

These pinchers 207 are carried by cross arm 208' mounted' on rod 209positioned by extension 210 beyond the cylinder 205. This rod 209 hasgear 211 thereon in mesh with blow table gear 9. This means that thepincher engaged ware at this take-olf station 13, after being lifted atonce the table 9 starts from this take-off position, has this ware ascarried by the pinchers 207 swung away from the table 10. Asthe nextarticle of ware comes to this station 10 and the walkingbeam 208l isdepressed to have the pinchers 207 engage such ware, the ware on theouter end of this cross arm 208 is released for deposit on the conveyoror other means for transporting or accumulation forI transporting to alehrv or place for annealing such ware.

As the mold sections 146, 147, pass from this take off station 13, theroller 164 rides from the cam portion 167 to the intermediate camportion 168 and elects a partial closingl o this blow mold. The extentof su'ch closing islimited by outer guide member 212 (Fig. 20). Thepartially closed moldf Ais accordingly in position at 'this station 14for passing to station 7 and there receiving the blank for a repetitionof this cycle of operations. Y

THE PowER'CoNTRoL.

Main power air supply.

214 extending to valve 215 (Fig. 10). 4 This power line 213 has4additional branch 216 extending to lock bar trip rocker valve 217, andbranch 218 extending to lock bar valve 219 (Figs. 3, 12). Branch 220from power line 213 extends to main valve 221.

' Table release.

When the transfer operation has been effected by the shifting of 'thecrosshead 52 from station 3 to station 7, and the return operation hasoccurred, guide rod 224 (Fig. 10) has stop 225 thereon strike dependingarm 226 and operate the valve 215 so that power air from the line 214may pass by line 227 and the valve 217 and shift such valve 217 so thatpower air from the line 216 may passthe valve 217 and go by line 228 tothe top 'of lock bar cylinder 229 (Figs. 3, 11, 12') thereby pullingdownward piston rod 230 and thus acting through lever 231 swinging onfulcrum 232 to depress lockv bar 233 from engagement with seat 234 inthe gear 7. The tables 6, 10, are, accordingly, released. This lever 231in this operation rocks arm 235 of lock bar valve 219,

Iand thereby allows low of power air from the line 218 to flow by line236 to the driving end of power cylinder 237 for ,thereby shiftingpiston rod 111 to travel into this cylinder 237. y

Station devices 'rendered idle.

Just before this supply of air from the lock bar valve 219 for drivingaction in the cylinder 237, this lock bar valve 219 connects line 238 toreceive power air from the line 218. This line 238 has branch line 239to blow up. cylinder 104 (Figs. 3, 8), thereby depressing the head 110to release the blowing up means from the blank mold at station 2. Branch240, from the line 238, extends to the top of cylinder 63 at station -1(Figs. 3, 6), and depresses piston rod 64 in the cylinder 63 forwithdrawing nipple head 241 and thus moving downward iange 107 forwithdrawing plunger 65 from the inwardly thrust position in the neckfinished at station 1. In those instances, wherein it is desired torelease the lass from following the plunger 65 or to ve a slight volumeof air to the blank at t is point, valve 242 may be adjusted to allowflow of air by duct 243 through the guide 106 and the plunger 65.

From the line 238, extends branch lines 244 to the front end of lockcylinders 72 (Figs. 3, 6, 8) for bringing jaws 75 into blank moldreleasing position in the movement of the piston rods 73 outwardly fromthe column 3. The line 238 has branch 245 to the front end of cylinder86 (Figs. 3, 6) eective for swinging cylinder 90 and its depending'cap94 away from position over the funnel 83 at station 1.

From this branch 245 there is branch 246 to the lower end of cylinder 90to eiect` lifting of the cap 94 clear of the funnel 83 at station 1. Theline 245 has an additional branch 247 extending to the lower end ofcylinder 111, station 2, for lifting the baille plate or cap clear ofthe blank mold. From the' line 238 is branch 250 to the bottom ofpincher operating cylinder 205 (Figs. 1, 3, 21). This eiiects lifting ofthe piston rod 206 clear of the pinchers 207. From this branch 250 arebranches 251 to the lower ends of blow cylinders 182 at stations 9, 10,and to the inner ends of blow mold locking cylinders 190. The hlowheadsare thus lifted clear ot the blow molds and the blow molds are unlockedat the blow stations 9, 10. Branch 252 from the branch 248 extends tothe bottom of neck finish opening cylinder 151 (Figs. 3, 10) to etfect alifting of the shoe 153 clear of the travel limit of the pin 152. Fromthe line 252 extends branch 253 to the back end of blank mold openingcylinder 136, which brings the lever depending portion clear of thetravel of the stem 40 as coming to transfer station 3. Branch 254 fromthe line 238 extends to the bottom of pincher lifting cylinder 255(Figs. 3, 21) to lift rod 209 and thereby clear the blown bottle fromits position on the blow table 10 after it is gripped by the pinchers207.

By the above series of operations all locks, or Yinter-connectionsbetween elements at stations, are released or opened and the action ofthe live air as entering the main driving cylinder 237 is effective forshifting opera tion by driving the piston rod 11 into the cylinder 237.This shifts the blank table 60 and the low table 45 to new stations ofrest.

Dri/ve stroke.

As this piston rod 11 moves on its inward stroke, pin 256 strikes arm257 on the main valve 221, rocking this main valve 221 to such extentthat power air from the line 220 passes by the line 258 (Figs. 2, 3,) tothe valve 217 shifting such valve 217 so that the power air from theline 216 instead of passing to the line 228 now passes to line 259 tothe lower end of lock bar cylinder 229. The line 228 is now free toexhaust through the valve 217. This effects a thrusting upward 0f thelock bar 233,'so that as the rack 12 finishes its stroke, this bar 233may ride into the next seat of opening 234 in the blank table gear 7fory locking such table against shifting. Mounted adjacent the pistonrod 11 is valve 260 carrying arms 261, 262. Pins 263 as adjusted inthe'desired opening 264 of the rack 12 (Figs. 2, 3) may coact forcutting oil flow of power air to the cylinder 237 and allow such powerair to be by-passed by branch 265 at a rate adjustable by valve 266 sothat while power air is supplied to the full end of its stroke suchpower air may extend t0 the full stroke action as insured by mamas thesupplemental decreased power air supily. This means that while the speedmay be maintained for driving operation there is minimized or actuallyeliminated any hammer tendency which might tend to arise from the supplyof power air to the full end of the driving stroke. l .i

In this operation of the lock bar valve 229,

for shifting the lock bar 233 intov table engaging position, lever 267(Figs. 11, 12) as acted upon by the lever 231 to swing on its fulcrum268 has lug extension 269 engage collar 270 on pin, 15 for pulling: thispin downward against the resistance of spring 16 for withdrawing head 47from opening 18. There is, accordingly, an unclutching of the segment 13from'the gear 8. This frees the rack 12 so that for the return stroke ofthe piston rod 11 outward from the drive cylinder 237, the collar 270 asriding off the lug 269 holds the head 217 clear of the ripening 18 inthe flange 19, but that such is released to enter the next opening 18,herein shown as 180o from the one just-unclutched.

Idle stroke and station operations.

This operation of the lock bar cylinder 229 and rocking ofthe lever` 231also rocks the arm 235 on the valve 219 repositioning this valve so thatpower air 4from the line 218 isv A 275 permits a jet or puff of air tobe supplied through the neck finish of the blank at station 2 forblowing the molten glass into the blank mold and forming a slight recessadj a' cent the neck finish in the formation of the blank. The `actionof the air from the-line 273 in lifting the nipple 241 at station l isto' effect closing of the lower portion of the blank mold at thecharging station 1, as well as thrusting of the plunger up into the neckfinish. v y

From this line 271 extends branches 276 to the outer ends of lockcylinders 72 at' stations 1, 2, for lthrusting the piston rods 73 towardthel column 3, thereby to effect swinging of the locking jaws into blankmold locking position at these two stations.

At the stations of rest ofthe tables as now locked, it is in order toopen the blank mold sections 29, 30, at station 3. To this end, the line271` has branch 277 extending to the front end of blank opening cylinder136 to effect a swinging of the lever depending portion 140 toward thecolumn 3 to engage the stem 40 and thereby pull the sleeve 39 andoperate through the links 35 for swinging-the blank mold sections 29,30, into open position at thetransfer station. This .extends lbranch 281to the upper end ofv baffle plate carrying cylinder"111 at station 2, to

effect thrusting of the baiile plate 120 into sealing position atstation 2.

Line 278 has branch 282 to the outer end of mold opening cylinder 200 atthe take-off station effective for shifting the piston rod Y 201 inwardand through leve-r 202 (Figs. 3,

20) pulling the crosshead 163 vfor opening the blow mold sections 146,147, at the takeoff station. Branch 283 from the line 271 extends to thetop of pincher lifting cylinder 255 for lowering the pinchers toward theware as thus exposed at the take-ofi" station.

Branch 284 from the line 271 to the upper end of pincher closingcylinder 205 brings thepinchers 207 (Figs. 3, 21) into ware grippingposition at the take-off Station.

This branch 271 has -branch 286 to the main valve 221 which-is timed bysaid machine valve for permitting flow of air from this main valve 221by line 287 lto the back end of transfer effecting cylinder 141 (Figs.3, 10). This line 287 is opened by valve 288, which valve 288 isoperated by pin 289 rising from the lever 138 thereby insuring that themolds 29, 30, are fully opened before the transfer cylinder 141 maythrust its piston rod 142 outward in shifting the crosshead 52 from thestation 3 to the station 7.

1n the travel of the crosshead 52 away from the disk 21, stop 291strikes depending arm 292 (Figs. 3, 10) and resets the valve 215 so thatlive air from the line 214 may pass by the line 293 as adjusted by valve294 to the back end of-cylinder'169 for effecting thrusting of thepiston rod 170 outward and therebythrough the lever 171 effect closingofthe blow mold sect-ions at the transfer station 7 about the blank assuspended thereopen the finish 54, 55, and release the blank into theblow mold at station 7. From the line 293 extends branch line 297 to theback end of cylinder 86 for swinging the cylinder 90 over the funnel 83.In this swinging operation, valve 298 is struck to open and supply powerair from the line 213 through branch 299 in the line 213 to flow by line300 to the upper end of cylinder90 for thereby lowering closure cap 94upon' the funnel 83 at station l.

This power line 299 has branch 302 (Figs. 3, 6) to chamber 303 in thestem 92. This chamber 303 is normally closed by' valve 93. As the pistonrod 91 descends and brings the cap 94'into seating position on thefunnel 83, the valve 93 is unseated to give packing or blow down actioninthe funnel 3, and the blank molds 29, 30, at station 1 to thus packthe charge of molten glass down in the blank molds about the blank informing the neck finish.

`When the rack 12 has travelled on its drive. stroke about one-fourthdistance inward, the lug 256 strikes linger 304 of valve 305 and therebyconnects power air from line 236 by way of branch 306 as extending tothis valve 305 for passing therefrom by line 307 to the inner end ofblow mold closing cylinder 169 at the transfer station thereby to resetthe lever 171 at station 7. This line 307 has branch 308 extending tothe back end of cylinder 200 at the take off station for thrusting thepiston rod 201 outward resetting the lever 204 at station 13.

When the drive rack 12 in its reverse travel approaches the end of itsidle stroke, the pin 256 strikes arm 309 on the valve 305 and resetsthis valve 305 so that power air from the line 213 may pass by line 310to the valve 305, and thence by line 311 directly to the valve 215.W'hen the full return stroke has been accomplished at the transferstation, this valve 215 has been so shifted that this supply of'air fromthe line 311 may pass this valve 215 to line 227 extending to the valve217, resetting this valve 217 for a repetition of this cycle ofoperations.

The timing of the travel of the rack 12 may be adjusted not only by thevalve 266 i but also by valve 313 as such may check the rate of powerair travel in exhaust as check valve 314 precludes blow of exhaust airfrom the cylinder 237 in the outward stroke of the piston while checkvalve 315 precludes flow of power air from the cylinder 237 in theinward stroke of the piston. Branch 316 from the cylinder 237 has itsexhaust adjusted by valve 317, and this is another factor in controllingthe speed of operation or timing for a repetition of this cycle ofoper-.1- tions, in the machine of this disclosure. This exhausting ofair from the various cylinders as receiving power air from the valve 219is back through this valve 219, and such is there muffled or quieted bypassing into exhaust receiving mufiler 318 (Fig. 14) located medially ofthe machine extent for there spilling the cool fresh aill and therebypromoting ventilation at the machine by causing circulation of the warmair away from the machine. 1f it be desired to have a different timingas by the feeder, the line 311 may extend say to a point adjacent thefeeder and have the valve 319 therein controlled by the feeder.

Shields or guards 320 (Figs. 2, 11, 12) preclude breakage of glass atthe transfer station falling down to clog the gear teeth. These guards320 thus serve as gear clearing means.
